How to keep your ice clean

When making or handling ice, the below precautions should be taken. Do not store anything but ice in the ice machine storage bin so that there is no potential for contamination. Not even the scoop. Always be sure to wash your hands before handling ice or utensils that touch the ice. Only use the handle of the scoop when retrieving ice. Never handle ice with bare hands. The scoop should be kept outside of the bin in a sanitary location between uses. Employees should never use the cup or glass for customer use as a scoop. Never put ice that is unused back into the ice holding bin. Instead, discard it and start with fresh ice. All ice handling equipment such as scoops should be washed daily in the kitchen dishwasher and sanitized properly according to health department standards. If you need to store some ice outside of the bin, make use of dedicated containers that are labelled “Ice only” so that they are only used for that purpose. These […]

Ice Cubes as clear as crystal from Impure Water

An ice cube machine does not freeze ice like an ice tray. Take a look at an ice cube from an ice tray and you will see a cloudy area in the centre. Then take a look at an ice cube made from a machine. You will see that it is clear all the way through. This is what allows it to make clean ice with dirty water. Here’s how. First, only pure water freezes at 32 degrees Fahrenheit. Impure water freezes at lower temperatures. The water around the outside of the cube is exposed to the coldest first and starts to freeze. The pure water freezes around the outside and pushes the minerals towards the middle. The mineral-laden water in the middle freezes last, making the cloudy ball in the middle of an ice tray made the ice cube. But the ice cube machine makes ice without the cloudy middle. How Ice Cubes Machines Avoid Freezing Impure Water An ice cube tray holds the water in place. The pure water freezes first and then the impure water freez […]

Condensers 101

Condenser, a device for reducing a gas or vapour to a liquid. Condensers are employed in power plants to condense exhaust steam from turbines and in refrigeration plants to condense refrigerant vapours, such as ammonia and fluorinated hydrocarbons. The petroleum and chemical industries employ condensers for the condensation of hydrocarbons and other chemical vapours. In distilling operations, the device in which the vapour is transformed to a liquid state is called a condenser. All condensers operate by removing heat from the gas or vapour; once sufficient heat is eliminated, liquefaction occurs. For some applications, all that is necessary is to pass the gas through a long tube (usually arranged in a coil or other compact shape) to permit heat to escape into the surrounding air. A heat-conductive metal, such as copper, is commonly used to transport the vapour. A condenser’s efficiency is often enhanced by attaching fins (i.e., flat she […]
